Remarks

Replaces the content of a child ImageView of a RemoteViews presentation template with the first image that matches a regular expression (regex).

Typically used to display credit card logos. Example:

new ImageTransformation.Builder(ccNumberId, Pattern.compile("^4815.*$"),
                                              R.drawable.ic_credit_card_logo1, "Brand 1")
                .addOption(Pattern.compile("^1623.*$"), R.drawable.ic_credit_card_logo2, "Brand 2")
                .addOption(Pattern.compile("^42.*$"), R.drawable.ic_credit_card_logo3, "Brand 3")
                .build();

There is no imposed limit in the number of options, but keep in mind that regexs are expensive to evaluate, so use the minimum number of regexs and add the most common first (for example, if this is a tranformation for a credit card logo and the most common credit card issuers are banks X and Y, add the regexes that resolves these 2 banks first).
